WHAT IS TYPE B ROOF DECK?

B Deck is by far the most commonly used roof deck for new construction projects. This is due to the fact that B deck is the most efficient 1.5”deep steel roof deck section. Compared to Type A roof decks and Type F roof decks, Type B metal roof decks have the highest strength-to-weight ratio. As with all steel products, the lighter the section, the more economical it will be. And since Type B roof decks can carry higher loads at longer spans than A decks and F decks, the steel supports below the metal deck can be spaced further apart. The result? A larger support spacing results in fewer supports and more savings for the building owner.

Here is one standard B deck for your reference:

As previously mentioned, Type B deck is the most commonly used roof deck for new construction projects. In comparison to other roof decks such as Type A and Type F, Type B roof decks have a higher strength-to-weight ratio, are more economical, and can carry higher loads at longer spans. Given that steel supports can be spaced further apart with Type B decks, building owners can save money by purchasing less supports

Type B deck is a wide-rib roof deck ideal for a wide range of applications

Type B, wide-rib structural roof deck is a high-performance, cost-efficient choice with a variety of options to meet multiple project needs. Standard or cellular, acoustic or vented, interlocking or nested side laps, B deck is among the most flexible of our 1½-inch deep roof decks.

Standard B Deck

Type B roof deck provides the best balance of strength and economy of all the 1½-inch-deep roof decks. Where rigid roofing insulation is used with B deck, a minimum 1-inch thickness is required.

We design the Steel roofing decks machine as following:

Based on understanding of Type B (B-deck)Metal Roof Deck 80 (Wide Rib) understanding, we design the machine like this:

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Thick cutter holder to protect the cutter holders for long time to use.For the shaft and rollers, normally  uses very strong shaft and big diameter rollers with gear inside , for making higher speed and better rolling effect.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

For some heavy duty rollers, we will put gear outside, then it can feed the coil to machine easily.
